Avantio’s PMS includes automated guest communications, so registration can run hands-free. Best Guest connects in two ways:

  • Automated messages — Avantio automated guest emails/messages deliver your registration link.
  • iCal sync — Best Guest imports every reservation Avantio manages.

Estimated setup time: 5–10 minutes.

Before you start

  • An active Avantio account
  • A Best Guest account
  • Your Best Guest registration link, e.g.
https://bestguest.app/l/your-listing?channel=avantio

(Use your real link. ?channel=avantio records the reservation origin.)

Using the right link: every listing — each apartment, room, tent, RV, or whatever counts as your smallest bookable unit — has its own unique registration link. If you manage more than one listing, double-check you’re copying the correct one. Find all your links in Best Guest under Properties → [property] → Listings → Copy listing link, or grab them during the Listings step of onboarding.

Path 1 — Automated message

  1. Open Avantio’s Harmony (the PMS’s communication-automation section) and create a new automation of type Booking Solution.
  2. Configure its trigger and send time (e.g. 2 days before arrival), add your message, and insert Avantio’s guest-name placeholder from the editor.
  3. If you want a different message per OTA, apply a tag filtered by portal (Avantio’s tags can also filter by property or booking type).
Hello (guest name),

Before arrival, please complete your online guest registration:
https://bestguest.app/l/your-listing

It takes under 2 minutes. We look forward to welcoming you.

Best Guest automatically reminds the main guest if they started registration but haven’t finished it. If a guest never opens the form at all, though, that reminder can’t reach them — so it’s worth scheduling a second automated message, timed 1 day after arrival instead of before it, using only the link:

Hello (guest name),

Everything alright? Did you fill out all your forms and is the data correct?
Please follow this link if you still need to add/change some information:

Path 2 — iCal sync

Avantio’s Channel Manager includes an iCal Import & Export feature that syncs connected channels in real time, though the exact in-product navigation isn’t publicly documented and it isn’t confirmed whether the feed covers every connected channel or just one listing. To import Avantio reservations into Best Guest’s Reservation Verification, check your Channel Manager settings for the export option, copy the iCal link, and paste it into Best Guest.

  • Reservation confirmed → confirmation only
  • 2 days before arrival → registration link
  • Arrival day → access instructions
  • 1 day after arrival → reminder for guests who haven’t completed registration
  • Departure → checkout reminder

Troubleshooting

Message didn’t send — confirm the automation is enabled, the timing, and property assignment.

Reservation missing in Best Guest — verify the URL and ?channel=avantio.
